【Portable Mini Pump】The electric bike pump with a size of only 64 x 56 x 28mm is specially designed for bicycles and can pump two 700 x 25cc tires from 0-80PSI when fully charged. A weight of less than 100 grams does not additionally burden the ride. It makes tire pumping more convenient and faster during long journeys. 【Easy Operation】The mini pump uses a high-performance motor and the inflation time varies from 50 to 160 seconds depending on the tube model. It can be inflated up to 100 PSI. It takes about 50-60 seconds for a 700 x 25c tire to go from 0-60 PSI. A 700 x 25 C tire takes about 150-160 seconds from 0-100 PSI. 【Rechargeable】The pump is equipped with a TYPE-C charging cable, which is rechargeable. It only takes 25 minutes to fully charge the pump. After the test, 200 tubes are inflated, and the inflation time does not slow down by more than 10%. 【Compatible with Schrader & Presta Valves】 No accessories are required and the Schrader valves and Presta valves can be switched quickly. 【Notes】 1. The package is equipped with a silicone protective cover. The pump will be hot during inflation. Please put on the silicone protective case. 2. If there is air leakage when inflating, please adjust the pressure angle in time. 3. There is a tugging sensation when the inner tube of the presta valve is inflated and removed. 4. Please keep the battery fully charged before use.
